Problems solved by technology

In the field of construction / road construction, hidden wells are concealed projects. The mortar used for masonry hidden wells is generally made of cement, sand and water, which has low strength and poor impact resistance; For laying, due to the existence of hidden wells, the degree of compaction by road rollers is generally lower than that of normal road surfaces, so the strength of the joints is low, water seepage is easy, and in many cases the well covers are not flush with the road surface, and vehicles make harsh "clang" impact sounds when passing, which affects Vehicle traffic and road landscape

Embodiment 1

[0026] A dry-mixed mortar for masonry of a hidden well is used for masonry of a vertical shaft, and its component formula is: 12% of cement, 85% of natural sand, and 3% of admixture.

[0027] The preparation method is as follows:

[0028] 1) Dry the natural sand until the moisture content is below 0.5%, sieve, send the particles larger than 4.75mm to the crusher, and send the rest to the mixer by weighing;

[0029] 2) The natural sand larger than 4.75mm is sent into the crusher and is crushed again, repeating step 1);

[0030] 3) Weigh the fly ash Portland cement with strength grade 32.5 into the mixer, and stir and mix for 1 minute;

[0031] 4) Methyl cellulose ether, polyhydroxy acid powder superplasticizer, alkyl silicate silicone waterproofing agent, C 12 h 25 N(EO) 7 (PO) 5 H organosilicon reinforcing agent is premixed according to weight percentage 0.1:0.05:0.05:1 to prepare admixture (total weight percentage is 3%), put into mixer and mix for 1min to obtain dry-mix...

Embodiment 2

[0034] A dry-mixed mortar for masonry of hidden wells is used for masonry and plastering of well covers and road surfaces, and its component formula is: 15% of cement, 80.5% of natural sand, and 4.5% of admixture.

[0035] The preparation method is as follows:

[0036] 1) Dry the natural sand until the moisture content is below 0.5%, sieve, send the particles larger than 4.75mm to the crusher, and send the rest to the mixer by weighing;

[0037] 2) The natural sand larger than 4.75mm is sent into the crusher and is crushed again, repeating step 1);

[0038] 3) Portland cement with a strength grade of 42.5 is weighed and sent to the mixer, and stirred and mixed for 1 minute;

[0039] 4) Mix the mixture of methyl cellulose ether and hydroxypropyl methyl cellulose ether (1:1), polyhydroxy acid powder superplasticizer, naphthalene powder superplasticizer, melamine superplasticizer and sulfamate Mixture of superplasticizer (1:1:1:1), mixture of alkyl silicate and polyalkylhydroxy...

Embodiment 3

[0043] A dry-mixed mortar for masonry of hidden wells is used for masonry of shafts of hidden wells in winter, and its component formula is: 13% of cement, 83% of natural sand, and 4% of admixture.

[0044] The preparation method is as follows:

[0045] 1) Dry the natural sand until the moisture content is below 0.5%, sieve, send the particles larger than 4.75mm to the crusher, and send the rest to the mixer by weighing;

[0046] 2) The natural sand larger than 4.75mm is sent into the crusher and is crushed again, repeating step 1);

[0047] 3) Weigh the ordinary Portland cement with a strength grade of 42.5 and send it into the mixer, and stir and mix for 1 minute;

[0048] 4) A mixture of hydroxypropyl methylcellulose ether, a mixture of melamine superplasticizer and sulfamate superplasticizer (1:1), a mixture of polyalkylhydroxysiloxane, and a silicone reinforcing agent C 12 h 25 N(EO) 7 (PO) 7 H is premixed according to the weight percentage 0.1:0.05:0.05:1 to prepar...

Abstract

The invention relates to a dry-mixed mortar for staple shaft masonry in the field of building / road construction and a preparation method thereof. The dry-mixed mortar comprises the following components by weight: 10-15 parts of cement, 75-85 parts of natural sand and 3-6 parts of additives. The ingredients are stirred well to obtain the dry-mixed mortar for staple shaft masonry. Compared with the prior art, the invention has the beneficial effects that: 1) the dry-mixed mortar prepared by the invention has the characteristics of high compressive strength, strong impact resistance, infiltration prevention, abrasion resistance, rapid hardening and freezing resistance; 2) the staple shaft has high strength, impact resistance and no collapse; the staple shaft cover is in compact conjunction with the road, is impermeable, levelling and beautiful in appearance, and can eliminate the harsh bang noise when vehicle passes through, so as to facilitate vehicle traffic; and 3) the usage cycle of the staple shaft is improved, and the maintenance and repair costs of the staple shaft are reduced.

Description

technical field [0001] The invention relates to the technical field of building / road construction, in particular to a preparation method of dry-mixed mortar for masonry in hidden wells. Background technique [0002] The underground well is the installation and inspection port of the urban underground pipe network. Urban water supply, sewage, rainwater, gas, electricity, telecommunications, northern heating and other underground pipe networks are generally laid along the road, and a dark well should be set up at the corner or at a certain distance to facilitate the installation of pipes, power, and communication facilities. Routine maintenance and repair. In the field of construction / road construction, hidden wells are concealed projects. The mortar used for masonry hidden wells is generally made of cement, sand and water, which has low strength and poor impact resistance; For laying, due to the existence of hidden wells, the degree of compaction by road rollers is generall...
